Soft limits prevent the lathe tool post from crashing into the chuck or tailstock by generating an emergency stop before hitting physical limit switches.
Whether you are restoring an older lathe, troubleshooting an axis runaway, or looking to optimize your communication settings, understanding the is critical.

While the manual is voluminous, operators and maintenance technicians often focus on a specific set of parameters for daily operation and troubleshooting. A. Axis and Rapid Traverse Parameters Fanuc 10t Parameter Manual
What are you trying to perform (e.g., setting up RS-232, adjusting axis drift, recovering home position)?
Press the key on the Fanuc panel. The CRT will flash "INPUT" in the bottom corner until data transmission is complete.
Ensure your cable pinout matches Fanuc standard RS-232 specifications (Null Modem config). Set your external PC software to "Receive" mode. On the Fanuc 10t, select mode. Press the SETTING function key, then the PARAMETER softkey. Soft limits prevent the lathe tool post from
Press the SETTING function key on the CRT panel.
Sets the Stop Bits (typically set to 1 or 2 ). Parameter 5112: Sets the Baud Rate. Common values include: 9 = 2400 Baud 10 = 4800 Baud 11 = 9600 Baud 2. Axis Movement and Overtravel Parameters
Locate the setting named PARAMETER WRITE (PWE) . Change the value from 0 to 1 . While the manual is voluminous, operators and maintenance
Press the (Output) softkey. The control will flash "OUTPUT" or "BLINK" in the corner while data transmits. 3. Step-by-Step: How to Enable Parameter Writing
Check the command multiplier parameters (such as Parameter 1820) against the original machine tool builder (MTB) data sheets. 6. Best Practices for Maintaining Legacy Fanuc 10t Controls
Internal memory corruption, frequently triggered by a dead memory backup battery.
Additional typical settings for the 10T include: , INPUT DEVICE = 1 , and OUTPUT DEVICE = 1 . Here, "1" corresponds to the MDI/CRT port using a DB25 connector. Keep in mind that port designations (1 or 2) can vary between machine builders.
